Focus on highly valuable content. Think about what makes your fans look good to their peers when they share your content (otherwise there's little incentive in sharing).

Once you build your page and drive your engagement up you can start building a list. Since the newsfeed algorithm would kill your reach if you're doing that in a post, I recommend you use Facebook tabs and embed your squeeze/sales page directly on your Fb page.

That's the best way to monetize a Facebook page: through a list built correctly, which you then focus on monetizing.

Here are some social media marketing tips to keep you on the right track across all your social media campaigns.

Planning – As discussed previously, building a social media marketing plan is essential. Consider keyword research and brainstorm content ideas that will interest your target audience.
Content is King — Consistent with other areas of online marketing, content reigns king when it comes to social media marketing. Make sure you are offering valuable information that your ideal customers will find interesting. Create a variety of content by implementing social media images, videos, and infographics in addition to classic text-based content.
Consistent Brand Image — Using social media for marketing enables your business to project your brand image across a variety of different social media platforms. While each platform has its own unique environment and voice, your business’ core identity should stay consistent.
Blog — Blogging is a great social media marketing tool that lets you share a wide array of information and content with readers. Your company blog can also serve as your social media marketing blog, in which you blog about your recent social media efforts, contests, and events.
Links — While using social media for marketing relies primarily on your business sharing its own unique, original content to gain followers, fans, and devotees, it’s also great to link to outside articles as well. If other sources provide great, valuable information you think your target audience will enjoy, don’t be shy about linking to them. Linking to outside sources improves trust and reliability, and you may even get some links in return.
Track Competitors — It’s always important to keep an eye on competitors—they can provide valuable data for keyword research, where to get industry-related links, and other social media marketing insight. If your competitors are using a certain social media marketing technique that seems to be working for them, do the same thing, but do it better!
Measure Success with Analytics —You can’t determine the success of your social media marketing strategies without tracking data. Google Analytics can be used as a great social media marketing tool that will help you measure your triumphant social media marketing techniques, as well as determine which strategies are better off abandoned. Attach tracking tags to your social media marketing campaigns so that you can properly monitor them.
